The idea of having a small device implanted under your skin can feel like one more overwhelming step in an already overwhelming health journey. But for most people going through chemotherapy, a port turns out to be one of the more practical, even reassuring, parts of treatment, sparing veins from repeated needle sticks and making each infusion considerably more comfortable.
Knowing exactly what to expect before, during and after placement can make this small procedure feel a lot less intimidating.
A chemotherapy port, often called a chemo port or port-a-cath, is a small device implanted just beneath the skin, usually on the upper chest, connected to a thin, flexible tube called a catheter that sits in a large vein near the heart. Rather than requiring a new needle stick in your arm for every infusion or blood draw, the port provides a single, stable access point that can be used repeatedly throughout your treatment.
When it is time for chemotherapy, a nurse accesses the port through the skin using a specially designed needle, delivering medication directly into the bloodstream through the vein. Because the port sits entirely under the skin, it can remain in place for months, or even longer, without needing to be removed between treatment cycles.
The chemo port insertion procedure is typically a minor, outpatient procedure performed by a surgical oncologist or interventional radiologist. Before the procedure, you will generally have some routine blood tests, and your doctor will review your medical history and any medications you are taking, particularly blood thinners, which may need to be paused beforehand.
You will usually be advised not to eat for a few hours before the procedure if sedation is planned, and you should arrange for someone to accompany you home afterward, since mild sedation is commonly used alongside local anaesthesia to keep you comfortable throughout.
Chemo port placement is generally a quick procedure, typically taking around 30 to 45 minutes from start to finish. It is usually performed under local anaesthesia, sometimes combined with mild sedation, so you remain comfortable but do not require general anaesthesia in most cases.
During the procedure, a small incision is made, usually just below the collarbone, and the port is placed beneath the skin before the catheter is guided into the vein and positioned near the heart using imaging guidance to confirm correct placement. The incision is then closed, typically with dissolvable stitches or surgical glue, and a small dressing is applied.
Recovery from chemo port placement is generally straightforward, with most people able to go home the same day. In the days following the procedure, you can expect:
Most people can resume normal daily activities within a day or two, with any specific movement restrictions around the port site limiting activity in the short term. Follow your care team's instructions about wound care, bathing and when the port can be used for treatment.
Infection is one of the main complications to be aware of, though a 2025 audit of over 400 chemo port placements in breast cancer patients found pocket site infections in less than 1% of cases and catheter-related bloodstream infections in around 3%. These findings suggest that infection remains an important risk to monitor, even though reported rates vary across patient groups and clinical settings.
Symptoms worth watching for and reporting promptly include:
Contact your care team promptly if you notice these symptoms. Fever or chills during chemotherapy can sometimes indicate a serious infection and require urgent medical assessment. Do not wait for symptoms to worsen before seeking advice.
Once healed, your port requires relatively little day-to-day care, though a few habits help keep it functioning well and reduce infection risk. Keep the area clean, follow your care team's instructions for wound care, avoid picking at or applying unnecessary pressure to the site, and attend scheduled flushing appointments if your port is not being used for an extended period. Flushing helps maintain the port's function according to your hospital's protocol.
Never hesitate to raise any changes you notice at the site with your care team. If the port becomes painful, swollen or difficult to access, seek medical advice rather than attempting to adjust or use it yourself.
A chemo port is a relatively minor procedure that can make a meaningful difference to comfort throughout chemotherapy, sparing you repeated needle sticks and making each treatment session considerably smoother. Knowing what to expect at each stage can turn an unfamiliar procedure into a more manageable part of your treatment journey.
At AS LifeLine Cancer Care Hospital in Delhi, the surgical oncology and interventional radiology teams provide chemo port placement as part of comprehensive cancer care. Book an appointment to discuss port placement and what to expect for your specific treatment plan.
